A recently deployed set of test virtual machines are impacting the performance of a company development team project datastore. The shared cache server appears to be suffering from storage congestion.
Storage I/O Control is already enabled on all company datastores.
Which two steps should the administrator take to improve the performance of the cache server? (Choose two.)
To improve the performance of the cache server, the administrator should configure storage shares and storage limits per virtual machine. Configuring storage shares allows the administrator to prioritize the cache server's access to storage resources over other virtual machines, ensuring it receives the necessary resources to perform efficiently. Additionally, setting storage limits per virtual machine can prevent other virtual machines from consuming an excessive amount of storage I/O resources, thereby reducing congestion and improving the overall performance of the cache server.

It's D & E, shares and limits. Passed with 500/500 today.
Answers are D. Configure storage shares per virtual machine. E. Configure storage limits per virtual machine. Passed with 500 today
Any tips for the exam
are there a lot of exam questions that come from this dump ?
VMware vSphere provides mechanisms to dynamically allocate storage I/O resources, allowing critical workloads to maintain their performance even during peak load periods when there is contention for I/O resources. The storage I/O resources available to an ESXi host can be allocated to that host’s virtual disks by setting disk Shares or Limits. To set Shares or Limits, from the vSphere Client right-click a virtual machine, select Edit Settings, choose the Virtual Hardware tab, expand Hard disk 1 (or whichever hard disk you want to configure), then set the Shares or Limit - IOPs to the desired value.

DE. I just passed the exam now. My Score was 492 and all the questions in my exam came from this dump.
Did you get the contributor access for the rest of answers?
D & E are correct
DE Correct - Passed 500/500 today 1-Mar-23
permission to ask, the exam taken is VCP7 or VCP8, I am preparing for the exam but still hesitant to take VCP 8 is there any suggestion?
You will earn VCP-DCV (2023) badge whether you pass the v7 or v8 exam. Note: v7 exam will retire on 31/Jan/2024. If you wish to take v7 exam, you must take it before 31/Jan/2024.
D & E are correct
DE it is! Renew to v7. this still came out . pass with 500/500.
I don't see how the path selection policy or a claim rule would be of any use in this situation. The data is still going to need a path to take regardless. This question is asking about the cache server and how to improve it's performance, so I wouldn't want to put any limits on it. If I was going to put any limits, they would be on the other VMs and that isn't what this question is asking. That leaves you with A & D.
I have to choose D & E based on this link. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.resmgmt.doc/GUID-25C3D9FE-3A9D-4739-AC75-16A9E0A3D9F0.html
"per virtual machine"
The correct answer is D & E + You cannot update a storage provider and manually configure shares or limits. So, (A) is out of the questions as it asks you to pick two answers. + Select a VM storage policy from the drop-down menu. If you select a storage policy, do not manually configure Shares and Limit - IOPS. + https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.resmgmt.doc/GUID-25C3D9FE-3A9D-4739-AC75-16A9E0A3D9F0.html
The correct answer is DE.
Reading the documentation better (Performance Best Practices for VMware vSphere 7.0 guide) , I agree with you that the answers are D and E
This question is asking how to improve the performance of the cache server, so we have not to put any limits on it.
